The yawn came after this line in President Obama's speech: "No single person can train all the math and science teachers we'll need to equip our children for the future, or build the roads and networks and research labs that will bring new jobs and businesses to our shores. Now, more than ever, we must do these things together, as one nation, and one people."

Obama had paused for applause when the camera cut to Sasha, her sister and her mom.

It's not the first time she has yawned while listening to her father. In 2008, she yawned during the Democratic National Convention with her head on her mom's lap.

Sasha knows how to make news, that's for sure. On Sunday, when Obama was officially sworn in, she congratulated him by saying, "Good job, Dad. You didn't mess up."
